The Oura Ring 4 is a premium smart ring designed to deliver advanced health tracking in an elegant and discreet form factor. Finished in Ceramic Midnight and supplied in Size 9, this lightweight wearable continuously monitors key wellness metrics while remaining comfortable enough for 24/7 wear, making it ideal for users focused on sleep, recovery, fitness, and overall wellbeing.
Using advanced sensors and intelligent health algorithms, the Oura Ring 4 tracks heart rate, activity levels, movement, recovery, and readiness throughout the day. The collected data is presented through the Oura app, helping users gain valuable insights into their physical performance, daily habits, and long-term health trends.
One of the ring's most popular features is its comprehensive sleep analysis. It monitors sleep stages, duration, quality, and recovery patterns to provide detailed reports and personalised guidance. This allows users to better understand their sleep habits and make informed decisions that support improved rest and recovery.
The Oura Ring 4 supports both iOS and Android devices and offers up to 8 days of battery life on a single charge. Due to its non-standard fit, sizing should be confirmed using a compatible Oura sizing kit before purchase. Combining premium materials, long battery life, and industry-leading health insights, it is one of the most advanced smart rings available.
Second time bought from the buyer. Item arrives quickly and always well packaged. So always arrives in good condition. They even popped in a small pack of sweets. Would recommend this seller. Thank you.
This company has given me a bit of trust back to eBay. I might just search on eBay more as I switched to Amazon years ago. For buying on eBay, the headset works perfectly and was in pristine and boxed professionally. It was not in the original box but all wire's were sealed, and so was the headset. All was protected in bubble wrap. Again thanks to this seller who I have saved on my eBay for the future.
Best seller I have ever seen on eBay. Packed super safe, posted super fast (got it the next day!), honest, helpful & totally trustworthy seller. You really will not find better seller on eBay. Super professional & zero problems. 10/10 everything. Thank you.
Really enjoyed doing business with this company from start to receiving. Good customer service, arrived well in time. Would certainly recommend. Echo Spot new as described, works amazingly, looks good and price good too. Will certainly look on this company site again and would buy from them with no hesitation ????
At Rouge Technologies, we're redefining the way people and businesses buy, sell, and upgrade technology. We started in 2021 in a tiny bedroom. No office. No shelves. Just sellotape, storage under the bed and the belief that if we took care of our customers, the business would grow.
We specialise in new, used, and professionally refurbished tech, offering unbeatable value on everything from smartphones, laptops and gaming gear to accessories and gadgets. Whether you're after the latest devices or reliable refurbished options, our goal is to deliver top quality products at honest prices, all backed by expert support and fast dispatch times.
We also offer flexible trade-in services, making it simple for individuals and companies to turn their old tech into instant cash or credit. Our corporate solutions help businesses offload surplus or redundant devices and restock with new or refurbished equipment in a cost effective, secure and environmentally conscious way.
We rarely restock the same item twice, once it sells out, it's gone. To avoid missing out, we always suggest ordering while it's available.
Sustainability is at the heart of what we do. By extending the life of electronics through reuse and refurbishment, we help reduce e-waste and minimise the environmental impact of tech consumption. Every item we handle is carefully tested and verified, ensuring you get performance you can trust, whether you're buying for home, work, or resale.
Due to multiple previous scams, at the discretion of Rouge Technologies Ltd, more information may be required about the individual making the purchase prior to dispatch such as confirmation of identification matching delivery address. For buyers with low feedback (30 or less) or negative feedback, orders will be accepted on a case by case basis. We reserve the right to request identification matching the shipping address and full name of the account holder.
PayPal and all major credit and debit cards are accepted. Items will only be sent the buyers verified address. All items have their serial numbers and other identifiers recorded and many precautions are taken against potential scams. We have seen all the different types of scams and will actively work to resolve and contact the police to begin an investigation to assist where a fraudulent order or claim is identified.
Cancellations:
Should you wish to cancel your order, please process this in eBay and reach out to our support team immediately. If your order has not yet been shipped, we will process your cancellation and refund without delay. If your order has already been dispatched, we will issue a refund once we have received the returned items in accordance with our Return Policy.
Invoicing & VAT:
As a reseller of both brand new and used goods, we purchase items under both the Global Accounting VAT Margin Scheme and the VAT Standard Rate Scheme. This means that not all our items show VAT separately on the invoice. To understand both the VAT Margin Scheme and the VAT Standard Rate Scheme in more detail, please see the UK Government website.
If a specific invoice is required, please reach out to us prior to purchase to ensure that we are able to provide you with the correct invoice.
